Cyanogen azide, N3CN or CN4, is an azide compound of carbon and nitrogen which is an oily, colourless liquid at room temperature. It is a highly explosive chemical that is soluble in most organic solvents, and normally handled in dilute solution in this form. It was first synthesised by F. D. Marsh at DuPont in the early 1960s. There had been earlier reports of discovering it as a crystalline solid, which were incorrect.
